Add NIC properties to VM

[maumercado]

Hello Seba,

How do I add the network configuration to a NIC, for example make a NIC to be added to a VM, be Natted, bridged, host only etc?

Thank you

[Seba]

Hi!

   AFAIK, those NIC connection settings (natted, bridged, host only) are available for VMWare workstation VMs, not ESX/vCenter. In ESX you configure separetely different network objects, and then associate VMs to those networks.

I've written two very similar code snippets, the first reconfigures an existing NIC to use a different networw, the second add a new NIC to the VM

Cheers,

Seba.

Hi Seba ,

           How do i add a virtual switch to an ESXI Box . Can you share some code snippets for geeting this done ?
